Angular2 Error displaying System.config map with 404 error

Question

I am trying to map this Auth0 module to node_modules in my angular2 project using system.config in the index file. but i get 404 error in browser console

index file

<!-- 2. Configure SystemJS -->
<script>
  System.config({
    packages: {        
      app: {
        format: 'register',
        defaultExtension: 'js'
      },
      "/angular2-jwt": {
      "defaultExtension": "js"
      }        
    },
    map: {
      "angular2-jwt": "node_modules/angular2-jwt/angular2-jwt"
    }
  });
  System.import('app/bootstrap')
        .then(null, console.error.bind(console));
</script>

The console error is as follows

I included the script in the index file as follows

<script src="//cdn.auth0.com/js/lock-9.0.min.js"></script>

Following the instructions on the auth0 website for node.js / angular 2

I am trying to load the login button from the Appcomponent.ts template

Appcomponent.ts

import {Component} from 'angular2/core';
import {Router, RouteConfig, ROUTER_DIRECTIVES} from 'angular2/router';
import {AuthHttp,AuthConfig, tokenNotExpired, AUTH_PROVIDERS} from 'angular2-jwt';

import {HomeComponent} from '../home/HomeComponent'
import {AboutComponent} from '../about/AboutComponent'

declare var Auth0Lock;

@RouteConfig([
    {path: 'app/', component: HomeComponent, as: 'Home'},
    {path: 'app/about', component: AboutComponent, as: 'About'},
])
@Component({
    selector: 'my-app',
    /*template: '<router-outlet></router-outlet>',*/
    template: `
    <h1>Welcome to Angular2 with Auth0</h1>
    <button >Login</button>
    <button >Logout</button>
     `,
    directives: [ROUTER_DIRECTIVES]
})
export class AppComponent { 

    lock = new Auth0Lock('<<KEY>>', '<<Auth0_URL>>');

  constructor() {}

  login() {
    var hash = this.lock.parseHash();
    if (hash) {
      if (hash.error)
        console.log('There was an error logging in', hash.error);
      else
        this.lock.getProfile(hash.id_token, function(err, profile) {
          if (err) {
            console.log(err);
            return;
          }
          localStorage.setItem('profile', JSON.stringify(profile));
          localStorage.setItem('id_token', hash.id_token);
        });
    }
  }

  logout() {
    localStorage.removeItem('profile');
    localStorage.removeItem('id_token');
  }

  loggedIn() {
    return tokenNotExpired();
  }

}

Instead, you can try this configuration:

<script>
  System.config({
    packages: {        
      app: {
        format: 'register',
        defaultExtension: 'js'
      }        
    },
    map: {
      "angular2-jwt": "node_modules/angular2-jwt/angular2-jwt.js" <-----
    }
  });
  System.import('app/bootstrap')
        .then(null, console.error.bind(console));
</script>

, angular2-jwt node_modules/angular2-jwt/angular2-jwt.js ( ):

import {AuthHttp, AuthConfig, AUTH_PROVIDERS} from 'angular2-jwt';
